ReaderWriter::ReadResult now has a FILE_REQUEST enum.
ReaderWriter::Options now has a s/getAsynchronousFileReadHint() parameter methods.
libcurl based plugin now detects enabing of the AsynchronousFileReadHint, but
as yet does not handle async requests - handling everything syncronously.
DatabasePager now by default will enable AsynchronousFileReadHint for http
based file requests
There was a problem converting a file to Collada by using osgconv like this:
osgconv file.osg file.dae
You would get an error message:
I/O error : Permission denied
I/O error : Permission denied
error : xmlNewTextWriterFilename : out of memory!
Error: daeLIBXMLPlugin::write(file://cessna.dae) failed
Warning: Error in writing to "cessna.dae".
This was due to some bad URI processing code in the Collada plugin. The attached file fixes this by using the Collada DOM's URI processing functions. After this change the file will convert successfully in the local directory.

It might seem odd that the change actually removes the stub apply(Billboard&) method, but it turns out Billboards are easily supported in subordinate routines of the existing apply(Geode&) method with s dynamic_cast, so there's no need for a separate apply(Billboard&)."
I've spotted huge memory leaks int ShapeParser and fixed them.
Also, there was a missing destructor (PolygonM) and a missing member initialization (PolygonZ)
Would be nice if someone could test the changes.
To release the memory just if no reading error happened (and therefore the arrays would be valid) I've added an macro to release and reset the pointers at once. I'm not using macros myself very often as I don't like them, but I think it doesn't hurt in this code.

In essence, the FLT exporter was emitting a full set of Mesh records each time it encountered a PrimitiveSet.
Attached is a fix. The code now emits the Mesh set up records, then iterates over all PrimitiveSets and emits a Mesh Primitive record per PrimitiveSet.
It also loops over PrimitiveSets twice, first writing Face records according to the mode, the writing Mesh records (again according to the mode).
The final change included here is support for GL_POINTS as single-vertex Face records.
Billboards are still to come."
I removed QTtexture.h/.cpp and added QTImportExport.h/.cpp. I updated the CMake-files, I hope they are alright. I used the submitted code in my own apps since two months or so and it seems pretty stable, but as always the migration to the osg-quicktime plugin may have introduced new bugs, so perfect for developer release :)"
* Support for Vec4ubArray for color data
* Support for material transparency
Thanks to Neil Hughes, Jason Daly, yourself, and others for testing and reporting issues."
filesystem is case-sensitive. Here are the modifications needed to make
the compiler happy. These are only some include lines rewritten (Io.h to
io.h, Windows.h to windows.h etc.) for version 2.3.7."
Introduced code in BoundgingSphere, BoundingBox, ProxyNode and LOD to utilise the above settings.
Added Matrix::value_type, Plane::value_type, BoundingSphere::value_type and BoundingBox::value_type command line
options that report where the types of floats or doubles.
images with BGR order but not read them. My 2-liner fixed it for me
but it may be that someone with more knowledge of the plugin want to
insert more pixel formats in the reading part of the plugin."
requests for files in a archive are made with unix style paths. So to
be able to match an entry in map(_indexMap) it's keys needs to be
stored in unix style even on Win32"
Note from Robert Osfied, simplified this submission so that the added conversion to
unix slahes is done on all platforms as this should be safe and simpler to maintain.
Changes to existing files:
ReaderWriter.cpp -- to support writeNode() of course.
ReaderWriterATTR.cpp -- to support writeObject -- we write .attr files for textures, if they don't already exist.
AttrData.cpp/.h -- Minor fixes.
CMakeLists.txt -- to include the new files in the build."
From Robert Osfield, port to non Windows platforms just required fixing of header capitilization errors
that windows lets through the net due to having a case insensitive file system.
and a new scheme for computing the scaling when using autoscale that introduces smooth
transitions to the scaling of the subgraph so that it looks more natural.
help manage the scaling of particles, whether they should be relative to the
local coordiante frame of the particle system, or be in world coordinates.
1) Full DOS paths are now correctly opened by OpenVRML. A URL containing
a DOS path should be "file:///C:data/blah" rather than "file://C:data/blah".
2) The last primitive defined in "coordIndex" is now added if the
"coordIndex" is not terminated by -1.
3) Smoothed normals are computed if no normal field is provided.
Currently, there is no support for "creaseAngle", so all edges (even the
ones sharper than the creaseAngle) are smoothed. I might add this in the
future if demand rises.
4) If an IndexedFaceSet contains only triangles or quads then the
primitive type is set to TRIANGLES or QUADS, and the primset becomes
DrawArrays rather than DrawArrayLengths.
Question: I noticed that for DrawArrays you can still provide an index
array. Would the rendering be faster if I'd create DrawElements primsets
rather than DrawArrays? Phrased differently, what is the benefit of
using DrawElements over DrawArrays, as there is clearly not a one-to-one
mapping of these concepts to their OpenGL counterparts?
5) Objects are added to the transparent bin and blend mode is enabled
only if the transparency is nonzero. Rendered transparent objects no
longer write the depth buffer."
"texture" paths. This is to drop absolute paths that some
3d editors export (even AC3D itself!). But this also strips
directories of relative paths, which is wrong and contradicts
the ac3d reference implementation. (The reference implementation
doesn't strip anything, though, and so takes the absolute paths
as they are. Definitely not what we want.)
The attached solution checks absolute paths and only strips
those:
(1) A:\\foo\\bar.png -> bar.png (as before)
(2) /foo/bar.png -> bar.png (as before)
(3) foo/bar.png -> foo/bar.png (new)
(4) ../foo/bar.png -> ../foo/bar.png (new)

The files are:
include/osgSim/ObjectRecordData -- The new class. Derives from Object to support .osg IO.
src/osgPlugins/OpenFlight/PrimaryRecords.cpp -- Reads data into that class.
src/osgPlugins/osgSim/IO_ObjectRecordData.cpp -- .osg IO support."
From Robert Osfield, made the OpenFlight read object record data optional via the -O readObjectRecordData ReaderWriter option.
